the homogenous plates shown in the figure has a mass of 10kg and is subjected to a forec and moments alonf its edges. If it is supported in the horizontal plate by means of a roller at A , a ball and a socket joint at B , and cord at C , determine the components of reaction at the supports .
The Attempt at a Solution
I wanna ask about the total moment about y ' axis ,
it's -300(1.5) + 981(1.5) -200 +Tc(3) = 0
the 2ooNm is acted along the y axis , right ? why we should consider it at y 'axis ?
The moment about y given is 300(1.5) +981(1.5) –Bz(3) –Az(3) -200Nm = 0
i can undersatnd for y axis , but not for y ' axis ...
